Given:
Total savings = $400
Ratio of savings of Blake and Josh = 3:1
To find:
The saving of each.
Solution:
Let the savings of Blake and Josh are 3x and x respectively.
According to the question,
[tex]3x+x=400[/tex]
[tex]4x=400[/tex]
Divide both sides by 4.
[tex]x=100[/tex]
Now,
Savings of Blake = 3(100)=300
Savings of Josh =100
Therefore, the savings of Blake and Josh are $300 and $100 respectively.

A) 2x + 2y = 10
B) 12 + 4y = -44
Answer: y=-x+5 and y=-14 [tex]2x+2y=10 subtract 2x from both sides\\2x+2y-2x=10-2x \\2y=10-2x divide both sides by 2\\y=5-x rewriting using the commutative property\\y=-x+5[/tex]

There are 12 inches in a foot in april mrs Harris used 32 feet of ribbon for an art club in may she used 45 feet of ribbon how many more inches of ribbon did mrs Harris use in may than April
Answer: 156 inches
Step-by-step explanation:
12 inches = 1 foot
In April, Ms Harris used 32 feet of ribbon for an art club. We will convert this to inches. This will b e:
= 32 × 12
= 384 inches
In May, she used 45 feet of ribbon . We convert to inches.
= 45 × 12
= 540 inches
We now calculate the difference in inches. This will be:
= 540 - 384 inches
= 156 inches
Unghiurile ∢AOB și ∢BOC sunt adiacente suplementare, iar OM, respectiv ON, sunt bisectoarele acestora. Fie BD ⊥ OM, D ∈ OM și BE ⊥ ON, E ∈ ON . Demonstrați că: a) patrulaterul BDOE este dreptunghi. b) OB ≡ DE .
Answer:
Following are the solution to this question:
Step-by-step explanation:
[tex]\angle AOB + \angle BOC = 180\\\\\angle MON = (\angle AOB + \angle BOC): 2 \\\\[/tex]
[tex]= 180: 2 \\\\=\frac{180}{2}\\\\= 90^{\circ}[/tex]

[tex]\angle AOB = 60\\\\ \angle BOC = 120\\\\ \angle MON = (60 + 120): 2 \\\\[/tex]
[tex]= 180: 2 \\\\=\frac{180}{2}\\\\= 90^{\circ}[/tex]
In point b:
[tex]\angle BOC = 100\\\\\angle AOB = 80\\\\ \angle MON = (100 + 80): 2[/tex]
[tex]= 180: 2 \\\\=\frac{180}{2}\\\\= 90^{\circ}[/tex]

The greatest common factor of the whole numbers 56 and 16 will be 8.
What is the greatest common factor?Simply said, it is the biggest common element. The highest consistent element in the above example is 15, making 15 the greatest common factor amongst 15, 30, and 105. The biggest chunk of the common factors is called the "Greatest Common Factor" (of two or more numbers).
The numbers are given below.
56 and 16
The factor of the number 56 will be given as,
56 = 8 x 7
The factor of the number 16 will be given as,

Answer:
47 DEGREES
Step-by-step explanation:
AOB + BOC = 180 (STRAIGHT LINE)
THEREFORE
(3x + 124) + (6x + 29) = 180
9x + 153 = 180
9x = 27
x = 27/9
x = 3
THEREFORE
6x + 29
(6*3) +29
18 + 29
47 DEGREES = BOC
Carrie has 0.125 more than Larry, Larry has 3/4 more than Harry. In total they have 151. How much does Harry have
Harry has 49.792 units.
Firstly we need to translate sentences into mathematical expressions and then we proceed to solve the resulting system of linear equations:
1) Carrie has 0.125 more than Larry:
[tex]y = x + 0.125[/tex] (1)
2) Larry has 0.75 more than Harry:
[tex]x = z + 0.75[/tex] (2)
3) In total, they have 151:
[tex]x + y + z = 151[/tex] (3)
Then, we proceed to solve the system of equations by direct substitution and clearing the remaining variable:
[tex]x + (x + 0.125) + (x-0.75) = 151[/tex]
[tex]3\cdot x -0.625 = 151[/tex]
[tex]3\cdot x = 151.625[/tex]
[tex]x = 50.542[/tex]
And the remaining solutions are, respectively:
[tex]y = 50.667[/tex], [tex]z = 49.792[/tex]
Harry has 49.792 units.
